Despite Rowling’s pleas for fans not to argue over the tweet (which was about as ambitious as a Muggle trying to cast a spell, really), battle lines were drawn almost immediately.

On one side were those Potterheads who have forgiven the notoriously unpleasant Potions Master thanks to his posthumously revealed acts of heroism, and on the other were those who still can’t look past what a jerk he was to Harry and his classmates.

To be honest, I’ve never really understood why the issue of Snape’s redemption always seems to become such a talking point, let alone such a huge bone of contention. To me, not only is Snape one of the most fascinating characters in the Harry Potter series, he’s also – glaring personality flaws included – one of the most heroic.
